A couple of weeks ago, Microsoft filed for the rights to claim the trademark "Throne Together" with the U.S. Patent and Trademark Office. The filing was made for the use of "Game software" so naturally we assumed it was for an upcoming Xbox or Windows game.

Microsoft's description says that the game tests a player's ability to construct castles that are able to withstand a number of environmental and location issues, such as rivers, geysers, steep mountains and more. Players can also reinforce their block castles but they also must be careful as they are building the structures as poor positioning or top heavy blocks can bring a castle down before it's finished.

Gamers can pick different modes of play in "Throne Together" including levels where only a limited number of moves are allowed, or trying to complete their castles before time runs out. The game lets people connect to Facebook to watch friends play their own levels.

Microsoft recently released its first "hardcore" Windows 8.1 game, the military air simulation "Cold Alley", but "Throne Together" is definitely an example of the type of casual game that users of Microsoft's OS are used to.
